Este trabalho tem como objetivo discutir alguns aspectos relacionados ao segundo Objetivo de Desenvolvimento Sustentável da Organização das Nações Unidas (ODS2): “acabar com a fome; alcançar segurança alimentar e melhoria nutrição promover agricultura sustentável”, especialmente, sob perspectiva fome pobreza no campo, por meio uma pesquisa bibliográfica-documental, intuito retomar as discussões...
Orphan drugs (ODs) are intended for the diagnosis, prevention, or treatment of rare diseases. Many cancer subtypes, including all childhood cancers, are defined as rare diseases, and over one-third of ODs are now intended to treat oncology indications. However, market access for oncology ODs is becoming increasingly challenging; ODs are prone to significant uncertainty around their cost-effecti...
conclusions higher ods score in females who had c/s showed that c/s could not protect the pelvic organ from pregnancy and delivery trauma. it seems that episiotomy has a protective effect during vd; it can reduce the severity of trauma in pelvic organs during childbearing. results in 30 consecutive females undergoing starr for the treatment of ods, who enrolled in this prospective study, 19 (63...
1-C and 2-C-branched carbohydrates are present as substructures in a number of biologically important compounds. Although the synthesis of such carbohydrate derivatives is extensively studied, the synthesis of 1,2-cis-2-C-branched C-, S-, and N-glycosides is less explored. In this article a synthetic strategy for the synthesis of 1,2-cis-2-C-branched-aryl-C-glucosides is reported via a hydrogen...
Obstructed defecation syndrome (ODS) is a functional disorder commonly encountered by colorectal surgeons and gastroenterologists, and greatly affects the quality of life of patients from both societal and psychological aspects. The underlying anatomical and pathophysiological changes of ODS are complex. However, intra-rectal intussusception and rectocele are frequently found in patients with O...
The facile regioselective synthesis of the P(iii) substituted thiazol-2-thione 2 is presented. Reaction of 2 with hydrogenperoxide-urea, elemental sulfur and selenium resulted in P(v) chalcogenide thiazol-2-thiones 3-5. All compounds were characterized using (31)P, (1)H, (13)C NMR, IR and elemental analyses and, additionally, by the single-crystal X-ray diffraction technique. Oxidative desulfur...
Desulfurization of fossil fuels demands a high technology as the crude oil is very complex mixture of molecules with a largest hydrocarbons form in composition. Hydrogenic method for desulfurization, takes higher cost and energy and also sulfur is not separated completely from heterocyclic poly-aromatic compounds. Researchers are focused on the use of microbial desulfurization [Biodesulfurizati...
This study shows the ability of sodium humate from alkaline treatment sludge on removing sulfur dioxide (SO2) in the simulated flue gas. Experiments were conducted to examine the effect of various operating parameters, like the inlet SO2 concentration or temperature or O2, on the SO2 absorption efficiency and desulfurization time in a lab-scale bubbling reactor. The sludge sodium humate in the ...
The possible application of imidazolium ionic liquids as energy-efficient green material for extractive deep desulfurization of liquid fuel has been investigated. 1-Butyl-3-methylimidazolium chloride [BMIM]Cl was synthesized by nucleophilic substitution reaction of n-methylimidazolium and 1-chlorobutane. Molecular structures of the ILs were confirmed by FTIR, (1)H-NMR, and (13)C-NMR. The therma...
